Enable Workspace.

The first "Feature" that attracted me to Ubuntu was the multiple workspaces thing, I know, it's kind of silly but workspaces are still very important to me.in Ubuntu 13.04 the workspace is disabled, but you can enable by going System settings>appearance (Behaviour tab) Tick on enable workspace.

Medibuntu is a packaging project dedicated to distributing software that cannot be included in Ubuntu for various reasons, related to geographical variations in legislation regarding intellectual property, security and other issues, some examples of packages included in Medibuntu we find libdvdcss package from VideoLAN, FFMpeg codecs not supported in multiverse, and the external binary codecs package (commonly known as w32codecs) used by MPlayer and xine.

Most of time i use firefox as default browser in Ubuntu, but the second choice for me is chrome.

A recurring question that I face is; what is the trick to download videos from youtube?

And I am quite sure that on reading the title “Youtube tricks” the first question that pops up in your mind too, is how to download videos from youtube. In this blog post I will try to explain some tricks to download youtube videos, as well as some URL customization tricks, through which you can easily do extra things on youtube.

How to download Videos from Youtube?

Google doesn’t want anyone to download videos from youtube, because of which there is no “Download” button on youtube. But there may be a situation wherein, it is required for you to download videos from youtube. Probably your Internet connection is slow, or, you want to watch videos later, at a time when you do not have an internet connection.

Well Download helper is an extension available for firefox which helps you to download videos from most of the video streaming websites.

After installation, the download helper icon will appear on the left corner, near the address bar.

Wherever you watch a streaming video the icon will start blinking.

On clicking the Icon you will get various download options.

It must be seeming very simple to download videos from firefox using downloadhelper. But, google chrome or any other browser does not support download helper, what then?

Use pwnyoutube, it is an even simpler URL trick to download youtube videos. All you have to do is just change “youtube.com” with “pwnyoutube.com” in the video address bar and hit enter.

The video will open in pwnyoutube.com and will give you a download option wherein you can download the video in MP3, MP4 and FLV formats.

How to go to a specific time within a youtube video?

Let us assume that you are watching an interesting educational video, 45 mins in length, and, the first time you watch only 5 mins 30 seconds of the video. The next time you open the video, you want to resume watching from 5 mins 30 seconds.All you have to do is add “&t=XmYs” at the end of the address bar. Replace “X” with the number of minutes and “Y” with number of seconds.
As per the earlier example you need to put “&t=5m30s” at the end of the youtube link.

How to repeat Videos on Youtube?

Almost any song you want to listen to is available on youtube. Many times I see, people replay videos after it stops playing, as youtube does not provide the option to repeat videos. Use youtuberepeater.com to repeat videos or songs. In the address bar change youtube.com to youtuberepeater.com and hit enter.

The website youtuberepeater.com will automatically repeat the video. You may also use this website to have a custom start or stop time for any video.

How to Create Video Mashups?

Have you ever wanted to play multiple youtube videos at the same time? It is not possible to do same on youtube. In order to play multiple videos at once, you can create mashups. For example - pairing a marathi laavni with sheela ki javani, wherein both the videos will start playing at the same time, you can also share the link with a friend to see your mashups.

The website youtubedoubler.com palys mashups video, all you have to do is enter the address of the two youtube videos in the box at the bottom of the page.

Mozilla's Teach the Web course will run from May 2 to June 30. And because it's an open online course, it's easy to dive in and connect with others at any time. You can participate in weekly guided discussions, tackle hands-on activities, develop and remix teaching resources, and compare notes with other members of the Mozilla community

I am not getting in deep for what is cloud computing, I am trying to explain what are the benefits an normal user can take from of cloud technology.
Cloud storage is new way to store your personal data online same as like backup your data on dvd or usb but cloud storage provide less risk to loose data than any other second storage medium and you can access data any computer around the world which have internet connection.
Todays market giant such as Google docs, YouTube & flicker are using cloud computing.

Q. As a computer user how this cloud storage help you?Ans. As computer user some data you require to have backup there is cloud storage comes in frame you don't require to put your backup disk any more your cloud will automatically update background.
Even you can sync your data between multiple computers and also access it on your mobile whenever its require. So no more usb and dvd you need to carry for data transfer on multiple system.

Q. how you can setup cloud on system.Ans. It's depend what kind of service you require and which OS. Here is some major free cloud storage provider.

Ubuntu One(In April 2014, Canonical announced that the cloud storage and synchronization features would be shut down)

After installation on your system it will create a folder which will sync with your dropbox account. All you need to drop your files and data on that folder it will automatically in background. Good when I want to share data with public and require the data should update periodically.

Google Drive: Good service provided by google 5GB free storage haves google docs is best for online document service. But to bad is not have official linux support so drop google drive from my list but some time i use for google doc services online only when more than one person require to update same time.

One Drive this service is provided by microsoft up to 15GB free storage online microsoft document service. only issue that they don't have official application on Linux OS yes we can use Webdev but out of my list.

Ubuntu One: Canonical is stop this service but best cloud storage services provided canonical, 5GB free space 500MB from referrals, Cross platform OS support the best part is its inbuilt ubuntu & support seamless sync with my personal laptop and windows on work even i can access those files on the go using my android mobile.

The ubuntu one folder created in my home folder in ubuntu & office i have installed the application same folder i have sync in windows OS as per my requirement i have created sub folder in Ubuntu One folder for Doc, Pic, Entertainment & work by default current and working files save in those folder so it can easily accessible on other devices with up-to date data so no more pendrive to carry my work data to home or my personal data to work all is take care by ubuntu one.

So now it's time to move from traditional data backup to new cloud storage services.
